Reset the 99 ports still listed under sylvio@
Sylvio's last commit was 17 months ago, a full 5 months after all of his
ports could have been reset per policy. Given the push to complete
staging (48 ports are still unstaged, something like 70+ have already
been staged by other committers) and given that PRs are automatically
assigned but never addressed, it's better just to reset all the ports and
PRs so that it's clear to others that these ports are free to maintain.

Fix installation of ports that rely on cp -n for installing files. r245960
changed cp to exit with a non-zero exit code if the file exists and is not
overwritten thus causing ports to fail installing when e.g. trying to cp
.default -> .conf files that already exist.
We just ignore the error and continue, as we used to.

At the moment 1385 ports use BUILD_DEPENDS= ${RUN_DEPENDS} and 450
ports use BUILD_DEPENDS:= ${RUN_DEPENDS}. This patch fixes ports that are
currently broken. This is a temporary measure until we organically stop using
:= or someone(s) spend a lot of time changing all the ports over.
Explicit duplication > := > = and this just moves ports one step to the left
